Specification of Lettei'sPatent.

rammed Nov. a, i915.

Application led September 16, 1911. Serial No. 649,690.

To all whom t may concern.'

Be it known that I, Ciixiinns "iLLixir LAvEas, of 52 John street. city of Halifax, Province of Nova Scotia, Doiiiiiii'on of Canada, have invented certain'iiew and useful improvements in Detachable Heels, of which the following is aspecification.

T his invention relates to improvements in detachable heels, and the objects of ythe invention are to provide an inexpensive form of attaching device' by which the rubber, leather or other kind-of removable `heels may be attached and detached and held in attached position. f

[Another object is topi-Ovide an instrumentality7 of the class specified, which from an operative standpoint will in usage possess a high degree of efficiency and effectiveness and which. structurally considered,will be of the greatest possible simplicity, being composed of but a few parts, all adapted for being made-at a minimum of cost and individually so formed as to be capable of beiiig readily assembled iii a neat and compact arrangement for accomplishing the purpose intended.

Other objects and advantages will be in part /obvious and 'in part pointed out hereinafter. and with these and other ends in view, this invention accordingly7 consists in. the features of construction, combination of parts andarraiigeiiieiit of elements hereinafter more explicitly set forth as an exempli- 'pi'iiiciples involved in the invention.

1n order that this invention may be more fully understood and to be comprehensible to others skilled in the art, drawings illustratingfa convenient means of carrying out the same are' pointed out as a part of this specification, and while the controlling principles of the invention may be otherwise applied by modifications falling within the scope of Athe claim, the hereinafter disclosedembodiment is that which will ordinarily be preferable toA employ in practice. ln such drawings it is to be noted that like numerals refer to corresponding parts ,throughout vall the figures.

1n the drawings: Figure 1 is a perspective view showing'the heel of the boot diagiammatically with the attaching plate rigidly supported thereby. Fig. 2 is a similar4 View showing theco-acting attaching plate 'movement position with the end of the spring ltongue 50.

adapted to be secured to the detachable heel, (not shown). Fig. 3 is a view similar to Fin'. 1, showing a slightly modified form of the invention. Fig. 4' is a view lshowing theattacliin'g plate to be secured to a detachable heel and adapted to co-act with the attach- .ing plate shown in Fig. 3.

Referring to the forni of the invention illustrated in Figs. 1 and 9, A represents the attaching plate adapted to be rigidly supported from the permanent heel a, diagraminatically shown in Fig. 1 being conveniently formed of a tliiii sheet of metal having a U- shaped flange flS stamped out from the plate and having out-turned edges. The plate D is provided with a'Ushaped flange 49 similarly formed to that -lS iii plate A but with the exception that its edges are inturiied as 'plainly shown. j The plate D is adapted to be secured to a detachable heel (not shown) and through the medium of the plate D, the detachable heel may be removably fixed to the permanent heel by sliding it on fioni the front, the flanges 48 and 49 interlocking. The plate D is also formed with a'spriiig tongue 50 adapted to engage the end portion of the flange 48 to prevent retrograde To detach the heel, the spring tongue 50 is'desigiied'to be' forced downwardly b v means of a rotatable key 51 suitably jouriialed iii the plate A having a U- shaped bend 52 adapted to be downwardly turned to engage the tongue. The plate A is provided with an aperture 53 which normally accommodates the U-sliaped bend.

The forni shown in Figs. 3 and l is similar to that of Figs. 1 and 2, and dieis principally iii the arrangement of the interlocking flanges 55 and 56;' the flanges. on the plate A being tuiiied downwardly and inwardly and those on the plate being turned upwardly and outwardly. The key 51 is mounted directly on the bottom of the heel.

The spring tongue and the locking key shown in Figs. 3 and 4 are ada ted to interjection adapted to engage in a certain Yhat I claim as my in vention is A heel construction comprising a perma- 'nent heel plate secured to the heel and a detachable heel plate, the latter plate having a U-shaped recess, a locking member in said recess and a eoperating locking member on the permanent heel plate, means adapted to prevent lateral movement between the plates but permitting longitudinal movement, and a horizontal rotatable member on the permanent heel plate so arranged that the rotation thereof d'epresses the locking member to I )ermit'longitudinal movementl of the heel A plates.
